Abstract (en)

Provided is a shoulder joint prosthesis. The shoulder joint prosthesis may include an outer cup, a lining, a ball head and a humeral shank, and the outer cup, the lining and the ball head are nested in sequence. Herein, the outer cup may include an outer cup body and a first limiting convex wall configured at an opening of the outer cup body, the outer cup body has a first spherical inner cavity, the first limiting convex wall protrudes out of a center surface of the first spherical inner cavity, and an end surface of the outer cup body is lower than the center surface of the first spherical inner cavity. The lining may include a hemispherical housing body and a second limiting convex wall and a third limiting convex wall configured at an opening of the hemispherical housing body, the hemispherical housing body has a second spherical inner cavity for receiving the ball head, the second limiting convex wall and the third limiting convex wall limit the ball head to leave the second spherical inner cavity, and the hemispherical housing body is provided with a groove for avoiding the humeral shank. With the adoption of the technical solution of the application, the problem that an unrestricted artificial shoulder joint in the conventional art has poor stability during motion in case of deficiency of a bone structure and a rotator cuff caused by tumors or severe trauma.
